Description

Gegenstand der Erfindung ist ein Verfahren zum Zusammenballen und Abscheiden von Schwebeteilchen aus Gasen durch akustische und elektrische Behandlung in einem gemeinsamen -Raum.-Die Er-, findung besteht darin, daß für: die elektrische- A bscheidung der akustisch behandelten Schwebeteilchen schwingungsfähige Niederschlagselektroden' verwendet werden, deren Eigenschwingung gleich, oder annähernd gleich der Schwingungszahl der im Behandlungsraum wirkenden Schallwellen ist. Auf diese Weise wird erreicht, daß die Niederschlagselektroden in Resonanzschwingungen versetzt werden und der auf ihnen abgeschiedene Statib wirksam zum Abrutschen gebracht wird.The invention relates to a method for balling up and Separation of suspended particles from gases by acoustic and electrical treatment in a common space.-The invention consists in the fact that for: the electrical- Separation of the acoustically treated suspended particles, vibrating collecting electrodes' are used whose natural oscillation is equal to or approximately equal to the number of oscillations the sound waves acting in the treatment room. In this way it is achieved that the collecting electrodes are set in resonance vibrations and the Statib deposited on them is effectively caused to slide off.

Eine besonders starke Anregung der Niederschlagselektroden zum -Mitschwingen findet statt, wenn als Niederschlagselektroden Rinnen, insbesondere Schrägrinnen, verwendet werden, deren Flanken quer, etwa senkrecht zur Richtung der Schallwellen verlaufen.A particularly strong stimulation of the collecting electrodes to resonate takes place when gutters, especially inclined gutters, are used whose flanks are transverse, approximately perpendicular to the direction of the sound waves get lost.

In der Zeichnung ist eine Einrichtung zur Durchführung des Verfahrens in einem Beispiel schematisch dargestellt.In the drawing is a device for carrying out the method shown schematically in an example.

Abb. i ist ein senkrechter Längsschnitt durch den Behandlungsraum und Abb. 2-ein Grundriß im waagerechten Schnitt durch Abb. i.Fig. I is a vertical longitudinal section through the treatment room and Fig. 2-a plan in horizontal section through Fig. i.

Der Behandlungsraum i, in dem die akustische und elektrische Behandlung des Gases vorgenommen wird, enthält vorzugsweise an der Stelle des Gaseintrittes eine Beschallungseinrichtung 2, z. B. eine Ultraschallsirene an sich bekannter Art. In einer gewissen Entfernung von der Beschallungseinrichtung 2 ist die elektrische Niederschlagsein-richtung angeordnet. Diese besteht aus an einem Tragwerk 3 federnd aufgehängten bzw. abgestützten Niederschlagselektroden 4 und den an Hochspannung liegenden Sprühelektroden 6. Die Elektroden. 4 sind in an sich bekannter Weise als Rinnen, insbesondere Schrägrinnen, ausgebildet, deren Flanken, wie Abb.2 erkennen läßt, quer, etwa senkrecht zur Richtung der Schallwellen stehen. Der Räum zwischen den Rinnen .4 und der Wandung des Gaskanals i kann durch Querwände 5 gegen einen Gasdurchtritt abgeschirmt seien Der von den Niederschlagselektroden abgleitende Staub gelangt in den Bunker 7.The treatment room i, in which the acoustic and electrical treatment of the gas is carried out, preferably contains a sound system 2, z. B. an ultrasonic siren of a known type. At a certain distance from the sound system 2, the electrical precipitation device is arranged. This consists of precipitation electrodes 4, which are resiliently suspended or supported on a supporting structure 3, and the high-voltage spray electrodes 6. The electrodes. 4 are designed in a manner known per se as grooves, in particular inclined grooves, the flanks of which, as can be seen in FIG. 2, are transverse, approximately perpendicular to the direction of the sound waves. The space between the grooves .4 and the wall of the gas channel i can be shielded against gas penetration by transverse walls 5. The dust sliding off the collecting electrodes gets into the bunker 7.

Die Erfindung kann in den Einzelheiten beliebig abgeändert ausgeführt sein. Dies gilt insbesondere fier die Art und Anordnung des ,Schallsenders und die Anordnung und Ausbildung der Niederschlagselektroden. Wesentlich ist in jedem Fall, daß die Niederschlagselektroden schwingungsfähig sind, derart, daß ihre Eigenschwingung gleich oder annähernd gleich der Schwingungszahl der im Behandlungsraum wirkenden Schallwellen ist.The invention can be carried out modified in the details as desired be. This applies in particular to the type and arrangement of the sound transmitter and the Arrangement and design of the collecting electrodes. In any case, it is essential that the collecting electrodes are capable of oscillation, in such a way that their natural oscillation equal to or approximately equal to the number of vibrations in the treatment room Sound waves is.
